you cant get to the camp beacouse the brain of Raz is out of his head , you remember ? But it sucks that they did not give us a chance to come back to that town ... or just leave the stupid situation ! O.o

This sucks!! I had to pick brains and the scavenger items:( Now I can only play in all the levels inside the brains u.u There had to be a part after everything where you are just hanging around the camp ;_;

If you want to go back to camp, you've got to use the point of no return autosave, yeah. Depending on how much you completed before that, it can be a long way back. It was certainly longer than I thought for mine when I wanted to get the rank 101 achievement (it turns out I missed a challenge marker in the real world, so that's why I had to go back).

The PONR can be undone if you go to Lungfishopolis and get to the island with the boss battle (double jump off the skyscraper nearest to the island and mash your PSI Blast) this lets you back to the outside of the asylum where you can Lungfish Call to return to the camp

But I completed the Meat Circus' final boss battle and now I can't return to the start of the Meat Circus level, it plays the cutscenes for the end of the game, if anyone can fix this that'd be fab, i need rank 101/ 100% save
